Polyurethane based phase change material (PCM) was prepared using polyethylene glycol (PEG), isophoronediisocyanate and octadecanol via a two-step process. PEG and octadecanol served as phase change components. The structural characterization of PCM was performed by ATR-FTIR and 1 H-NMR spectroscopies. The latent heat, phase change temperature and thermal stability of PCM were characterized by differential scanning calorimetry and thermogravimetric analysis. The results show that PCM has an excellent energy storage capacity, suitable phase transition temperatures and great thermal stability at 100°C without leakage. PEG/octadecanol polyurethane PCM reached 126 and 95 J/g enthalpy values. To investigate the efficiency of the PCM in a biodegradable polymeric support, blend films were prepared by mixing PEG/ octadecanol polyurethane with the PLA. Films exhibited high light transmission. Elongation at break increased compared with pure PLA from 6 % to 87 %. In addition, tensile strength and modules of PLA/PEG-octadecanol PCM decreased. Water contact angle values of the films increased to 66 and 70°with adding polyurethane PCM. In conclusion, PLA/PCMs exhibited high thermal energy storage property and suitable phase change temperature as good as the PEG/octadecanol polyurethane PCM. Therefore, PLA/PCMs can be used in ranges between 10 and 55°C.

“…Oktay ve arkadaşlarının yaptığı bir çalışmada ise Nphidroksifenilmaleimid 3-isosiyanato propiltrimetoksisilan ile reaksiyona sokularak yeni bir alkoksisilan monomeri hazırlanmıştır. Yeni monomer, polidimetilsiloksan esaslı üretan akrilat oligomeri ve ex-situ olarak hazırlanan AgNp lerden oluşan karışım polikarbonat plakalara uygulanmış ve UV ile sertleştirildikten sonra antibakteriyel özellikleri invitro olarak incelenmiştir [31].

Bu çalışmada çok dallanmış poliglisidol oligomeri (PG) ve poliglisidol esaslı çok dallanmış üretan metakrilat (PGUM) oligomeri glisidol ve 2-izosiyanatoetil metakrilat (IEM) kullanılarak sentezlenmiştir. Oligomerlerin yapıları FT-IR ile aydınlatılmıştır. Daha sonra PGUM, Metakril-POSS, fotobaşlatıcı (Irg-184), çapraz bağlayıcı olarak trimetilolpropan triakrilat (TMPA) ve AgNO3 karıştırılarak hibrit nanokompozit film hazırlanmıştır. Hibrit nanokompozit filmlerin mekanik ve termal özelliklerinin yanısıra kaplama performansları incelenmiştir. Metakrilik grupların çapraz bağlanması, gümüş iyonlarının kararlı nanopartiküllere (AgNP) indirgenmesi ve AgNP'lerin nanokompozitlere dahil edilmesi için UV ışığı kullanılmıştır. AgNP'lerin oluşumu TEM analizi ile doğrulanmıştır. Hibrit nanokompozit filmlerin Gram-pozitif ve Gram-negatif bakterilere karşı antibakteriyel aktiviteside ayrıca gözlenmiştir.

“…The photopolymerization of phenylmaleimide-containing trialkoxysilane (PMTES) and polyurethane acrylate derived from polydimethylsiloxane (PDMS) in the presence of SN with subsequent hydrolysis gave hybrid systems with hydrophobicity subject to controlled variation, thermal stability, and bactericidal activity [29]. Materials with a similar set of properties were obtained by the photopolymerization of a sol obtained from PDMS with terminal triethoxysilyl groups and TSM, alkyl diacrylate, and PDMS-containing polyurethane acrylate [30].…”

The major methods for the preparation of silver-containing polymer composite nanosystems and the formation of their hybrid structure are examined. Special attention is focused on a new class of silver-containing hybrid systems, namely, organic-inorganic coordination polymers, obtained by the self-assembly of silver complexes. The effect of intercomponent interaction on the structure and properties of these hybrid composites was examined.The creation of new improved materials is an important goal of modern chemistry and materials science. Polymer composites with hybrid structure are among such materials and hold interest since they display a combination of properties characteristic for each of the inorganic and organic components [1-3] and, in some cases, unique properties related to the specific nature of their structure [4]. From a modern viewpoint, hybrid organic-inorganic materials are formed by the combination of components, differing in their chemical nature, on a molecular or nano level through formation of chemical bonds ((non)covalent bonds, hydrogen bonding, and donor-acceptor bonds) or weaker physical bonds (van der Waals and electrostatic interactions) [5]. Special attention is given to the stability of the nanodispersed components due to interaction between the nanophase and various stabilizers [6]. The interest in silver-containing hybrid polymer composite materials, including nanocomposites, which, by their very nature, are a priori hybrid systems, is attributed to a set of properties of the matrix itself, which often possesses hybrid structure, properties of silver in ionic and nanodispersed forms, and new properties related to the appearance of hybrid silver-polymer structures [7,8]. Special interest is presently found in bionanocomposites derived from biopolymers and silver nanoparticles (SN), which display specific physicochemical properties, in particular, electrochemical, photochemical, and catalytic properties highly dependent on the dimensions and polydispersion of the nanophase [9, 10] as well as biological activity due to the ionization of the metal atoms in the presence of H 2 O/O 2 and the interaction between the SN surface and functional groups of the various biomolecules [11].In light of the important role of the polymer matrix in formation of the major structural characteristics and properties of silver-containing hybrid systems, we should classify these materials according to their chemical structure.Composites with Silver Nanoparticles (SN) Dispersed in a Polymer Matrix with Hybrid Structure. The major distinguishing feature of such materials is the prior synthesis of the hybrid polymer matrix obtained due to the formation of chemical bonds between the organic and inorganic components with subsequent introduction of SN into the system. The synthesis of the SN may be either in situ or ex situ. 740040-5760/15/5102-0074
